Answer 1

Answer:

x = 0 or ± √ab

Step-by-step explanation:

Given----->

Sec⁻¹ ( x / a ) - Sec⁻¹ ( x / b ) = Sec⁻¹ ( b ) - Sec⁻¹ ( a )

To find-----> Value of x

Solution-----> 1) Plzzz see the attachment

2) We know that

Sec⁻¹ ( x ) = Cos⁻¹ ( 1 / x ) , applying it in 2nd step

3) Then we know that ,

Cos⁻¹ x + Cos⁻¹ y = Cos⁻¹ { xy - √(1 - x²) √(1 - y²) }

Applying it in 4th step then solving we get value of x

Additional information---->

1)

Cos⁻¹ x - Cos⁻¹y = Cos⁻¹ ( xy + √(1 - x² ) √( 1 - y² )

2)

Sin⁻¹x + Sin⁻¹y = Sin⁻¹ ( x√1 - y² + y √1 - x² )

3)

Sin⁻¹ x - Sin⁻¹y = Sin⁻¹ ( x√1 - y² + y √1 - x² )
